Hi, so i started my birth control on October 29 and me and my bf didn't wait the whole 7 days before having unprotected sex. And 10 days ago I started spotting and it was light brown and pink and only a tiny bit and the next day it was darker brown and a tiny bit red and only when I wipe. And then the day after that it was dark brown and this time it would be in my underwear but not a lot. And up to today it has slightly gotten lighter in color and lighter in flow and now its more of brown stringy or globby discharge. What does this mean? Most sites are talking about pregnancy or miscarriage.
